Abstract

A lighting device with an extended, non-punctiform light source, a reflector which conically surrounds the light source, and a lens for concentrating the emitted light is characterized by the fact that the lens is mounted so as to be capable of moving along an optical axis of the lighting device within a predetermined range of movement in such a way that the focal point of the lens in the direction of emission can be shifted at least into an area behind the notional apex of the reflector.
